Fortnite

The AMD Ryzen 7 5700X and Intel Arc B570 combination delivers a mid-table performance profile in Fortnite, with the data showing a clear relationship between the CPU's thread management and the game's engine demands. The measured frame rates across resolutions indicate that this pairing is consistently capable of producing playable results, though the specific balance shifts depending on the graphical load applied.

CPU Role

The AMD Ryzen 7 5700X is an 8-core, 16-thread processor based on the Zen 3 architecture, running on the AMD Socket AM4 platform. Its base clock is 3.40 GHz with a boost clock of 4.60 GHz, and it draws a 65 W TDP. The processor features a 32 MB shared L3 cache, with 512 KB of L2 cache per core. In synthetic benchmarks, the CPU achieves a multi-threaded score of 13184 points in Cinebench R23 and 10779 points in Geekbench's multi-core test. Single-thread performance is also notable, with a Geekbench single-core score of 2016 and a Cinebench R23 single-core score of 1499.

For Fortnite, the 5700X's 16 threads allow it to handle the game's background tasks and physics calculations without bottlenecking the GPU. The benchmark data shows that at 1080p with Low settings, the combo reaches 176 FPS average, which suggests the CPU can feed frames quickly when the GPU load is light. The processor's 3DMark scores further illustrate its threading capability: 6858 points with 16 threads and 5768 points with 8 threads, indicating that scaling from 8 to 16 threads yields a modest 19% improvement. This is relevant because Fortnite typically uses fewer than 8 threads for its main game logic, but the extra threads help with streaming and anti-cheat processes.

The CPU's position relative to its direct competitors is nearly identical in aggregate performance. The Ryzen 7 5700X has an average benchmark score of 27578, which is exactly matched by the Intel Core i5-12600K (0% delta). The AMD Ryzen 7 5800 trails by 0.2%, while the AMD Ryzen 5 7600X is 0.2% faster, and the Intel Core Ultra 5 125H is 0.3% ahead. These tiny margins mean that in CPU-bound scenarios in Fortnite, the 5700X will perform virtually identically to these rivals, with any frame rate differences being attributable to other system factors.

How This Combo Ranks

The combo rank for this specific CPU-GPU pairing in Fortnite is 2178 out of 2740 tested combinations. This places it in the lower-middle portion of the overall distribution, meaning that roughly 20% of tested combos perform worse, while about 80% perform better. However, this rank must be interpreted carefully, as it aggregates across all settings and resolutions. The data shows that the combo is more competitive at lower resolutions and settings, where the CPU's 8-core/16-thread configuration can shine.

When examining the percentile data for each component independently, the CPU sits at the 79th percentile among all processors, indicating that it is a relatively strong performer. The GPU, on the other hand, sits at the 65th percentile among all graphics cards. This mismatch suggests that in many Fortnite scenarios, the GPU is the limiting component, particularly at higher resolutions where the 10 GB of VRAM and 160-bit memory bus become more stressed. The combo's rank of 2178 reflects this GPU constraint, as many combos with weaker CPUs but stronger GPUs would outperform it in graphics-heavy settings.

The measured FPS data supports this interpretation. At 1080p Low, the combo achieves 176 FPS, which is a strong result. However, at 4K Ultra, the average drops to just 21 FPS, indicating that the GPU is struggling with the extreme load. The CPU's 79th percentile ranking suggests it could support higher frame rates if paired with a more powerful GPU, but as configured, the system's overall performance is limited by the Arc B570's capabilities.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of this combo's performance across three resolutions and four quality settings. At 1920x1080, the results are as follows: Low settings produce an average of 176 FPS, Medium settings yield 124 FPS with a minimum of 106 FPS and maximum of 143 FPS, High settings deliver 96 FPS, and Ultra settings drop to 64 FPS. This progression shows a clear scaling pattern, with each step up in quality costing roughly 30-40% of the previous frame rate.

Moving to 2560x1440, the averages are 112 FPS on Low, 79 FPS on Medium (with 67 FPS minimum and 91 FPS maximum), 61 FPS on High, and 40 FPS on Ultra. The drop from 1080p to 1440p is significant, averaging about 36% across all settings. At 3840x2160, the results are 59 FPS on Low, 42 FPS on Medium (with 35 FPS minimum and 48 FPS maximum), 32 FPS on High, and 21 FPS on Ultra. The 4K results show that this combo is only playable at Low settings, where it barely maintains 60 FPS.

The Medium settings rows are the only ones with complete min/max data, providing insight into frame time consistency. At 1080p Medium, the range from 106 FPS to 143 FPS indicates a spread of 37 FPS, which is a 30% variance from the average. At 1440p Medium, the spread is 24 FPS (67 to 91), and at 4K Medium, the spread is 13 FPS (35 to 48). This narrowing range at higher resolutions suggests that the GPU becomes more consistently loaded, reducing frame time spikes.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals the bottleneck characteristics of this combo. At Low settings, the average FPS drops from 176 at 1080p to 112 at 1440p (a 36% reduction) and then to 59 at 4K (a 47% reduction from 1440p). This steep decline indicates that the GPU is the primary limiting factor, as the CPU's performance remains constant across resolutions while the GPU's workload increases dramatically.

For Medium settings, the progression is 124 FPS at 1080p, 79 FPS at 1440p, and 42 FPS at 4K. The percentage drops are 36% and 47% respectively, matching the Low settings pattern almost exactly. This consistency suggests that the scaling is purely GPU-bound, with the CPU maintaining its ability to feed frames even at the highest resolution. The High settings show 96 FPS at 1080p, 61 FPS at 1440p, and 32 FPS at 4K, with drops of 36% and 48%. Ultra settings yield 64 FPS, 40 FPS, and 21 FPS, representing drops of 37% and 48%.

The fact that all settings show nearly identical percentage drops between resolutions indicates that the limiting component is the GPU across the board. If the CPU were the bottleneck, we would expect to see smaller percentage drops at higher resolutions, as the GPU becomes less loaded relative to the CPU's fixed capacity. Instead, the linear scaling suggests that the Arc B570 is fully utilized at all resolutions, and its performance ceiling is what determines the final frame rate.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's target resolution and desired frame rate. For competitive play at 1080p, Low settings provide the highest average of 176 FPS, which is well above the 144 Hz refresh rate common on gaming monitors. However, Medium settings at 124 FPS still offer a smooth experience with improved visual quality, and the minimum of 106 FPS ensures no significant drops below 100 FPS.

At 1440p, Low settings are the clear choice for high-refresh-rate gaming, delivering 112 FPS. Medium settings at 79 FPS are acceptable for 60-75 Hz displays, but the minimum of 67 FPS could cause noticeable stutters on a 144 Hz monitor. High settings at 61 FPS are borderline, suitable only for 60 Hz displays. Ultra settings at 40 FPS are not recommended for any serious gameplay.

For 4K, the only viable option is Low settings, which achieves 59 FPS. This is just below the 60 FPS threshold, so users may need to enable any available upscaling or accept slightly lower frame rates. Medium settings at 42 FPS and High at 32 FPS are not suitable for fast-paced Battle Royale gameplay. The data suggests that 4K is not this combo's strength, and users should either drop to 1440p or lower the resolution scale for a better experience.

GPU Role

The Intel Arc B570 is built on the Xe2-HPG architecture and the BMG-G21 chip, fabricated on a 5 nm process by TSMC. It features 2304 shading units, 144 texture mapping units, and 80 ROPs, with 18 ray tracing cores. The GPU operates at a consistent 2500 MHz for both base and boost clocks, with memory running at 2375 MHz (19 Gbps effective). The 10 GB of GDDR6 memory is connected via a 160-bit bus, providing 380.0 GB/s of bandwidth.

In Fortnite, the GPU's performance characteristics are clearly visible in the measured data. The 10 GB VRAM capacity is sufficient for the game's textures at all tested settings, as there are no signs of memory-related stuttering or texture pop-in in the benchmark results. The 380.0 GB/s bandwidth, however, appears to be a limiting factor at higher resolutions, where the frame rate drops sharply. The GPU's pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s provide theoretical limits that align with the observed scaling.

The Arc B570's benchmark scores show it is a capable mid-range GPU. In 3DMark Steel Nomad DX12, it scores 2649 points, while Geekbench results show 83514 for OpenCL and 96844 for Vulkan. The Passmark G3D score of 14195 places it in the 65th percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 3070 Mobile, has a nearly identical average score (0.1% difference), while the Intel Arc A750 is 0.1% faster. This indicates that the B570 is competitively positioned within its performance class.

The GPU's 150 W TDP and dual-slot design are modest for the performance offered, but the data shows that Fortnite at 1080p Low can fully utilize the GPU's capabilities, hitting 176 FPS. The 11.52 TFLOPS of FP32 compute power is sufficient for the game's rendering requirements, but the 160-bit memory bus becomes a constraint at 4K, where the frame rate drops to 32 FPS on High settings. This suggests that users should consider the Arc B570 as a 1080p and 1440p GPU for Fortnite, with 4K gaming reserved for Low settings only.
